To all whom it may concern.-

Be it known that I, EDUARD RUDoLr Bns- EMFELDER, chemist, a subject of the German Emperor, residing at Gharlottcnburg, Germany, have invented certain new and useful Improvements Relating to Transporting and Heat-Interchanging Appliances for Solid and Pasty Materials, of which the following is a specification.

The specification of my Patent No. 653,015 (July 3, 1900) describes a process for the continuous manufacture of mixed gas, in which the coal used. as the raw material is continuously supplied to a gas-extractor serving to expose the coal to the influence of a current of water-gas of high temperature flowing in a direction opposite to the travel of the coal.

For the continuous working of the said process the material must be guided through the gasextractor uniformly and continuously. In the process described in the said patent specification the transportation of the material takes place by turning the gas-extractor on its axis, which. has an inclined position, in. consequence of which the apparatus occupies a great height. Similar appliances are used also in chemical manufactures for simultaneously transporting solid or semisolid. materials and subjecting them to heat or gases. The said method of transportation has, however, certain defects which render it unsuitable for many purposes.

According to the present invention oscillating or vibrating conduits similar to the open troughs well known for the conveyance of certain granular materials are adapted for the simultaneous transportation and heating or coolingof granular or pasty materials. The movable conduit, which may have a round or an angular cross-section and may be placed in a horizontal or inclined position, is provided with a heating or cooling jacket which touches the conduit along the greater part of its length and takes part in the oscillating or vibrating motion of the same. According to the temperature of the gas orliquid contained in the jacket, the latter serves to heat or to cool the material transported by the conduit.

In the further description of the invention reference will be made to the accompanying drawings, which represent different forms of a transporting and heating apparatus embodying my invention.

Figure 1 is a vertical section of an apparatus representing the first type. Fig. 2 1s a section along line as of Fig. 1. Fig. 3 1s a vertical section of an apparatus representing the second type. Fig. 4 is a cross-section along line 3 y of Fig. 3.

In the type represented by Figs. 1 and 2 the apparatus is composed of two sections placed one above the other in the same vertical plane and adapted to treat the coal or other raw material one after the other. The upper section chiefly comprises a tubular main conduit 5, surrounded by anannular heating jacket 21, and the lower section chiefly comprises a tubular main conduit 9, surrounded by an annular heating ac'ket 17. The tube 5 is supplied with coal at one end by means of a feed-screw 1 and a jointed feed-tube 2 3 4i and delivers it at the other end through a j ointed discharge-tube 6 7 8 to one end of the tubular lower conduit 9, which delivers it at the opposite end through a jointed tube 10 11 1.2 to a tower 13, constructed as described in my Patent No. 653,015,1nentioned above. The heating-gases ascend through a tube 1 1 15 16 to one end of the jacket 17, which surrounds the conduit 9 on the greater part of the length, and delivers the heating-gases at the opposite end to a jointed tube 18 19 20, leading to the jacket of the upper conduit, and after having traveled from one end of the jacket to the other the heating-gases escape through a jointed tube 22 23 24C. The jacket 21, which forms with the conduit 5 a rigid. body, is mounted on a frame 25, extending almost the whole length of the jacket and supported by a series of axles 27 and wheels on rails 29, which .in their turn are supported by cross-girders 30. 26 designates the bearings for the axles 27. The lower conduit is supported in the same manner by a frame 25, axle-bearings 26, axles 27, rails 2.), and cross-girders. A rapid to-and-fro motion is imparted to the acketed conduits by known means. Figs. 1 and 2 show for the upper section a horizontal shaft 31, mounted below the upper conduit at right angles to the same, a cam 32, fixed on the said shaft, and a cross-beam or abutment 33, fixed to the frame opposite the cam 32, and an antagonistic spring 34, fixed to the frame 25 and one of the beams 30, while the lower section is set in motion by a shaft 35, the cam 36, abutment 37 in one direction and by the spring 38 in the opposite direction. Rotary motion is imparted to the shafts 31 and by means of belts and pulleys 39 and 40. As the travel of the granular material through the tubular conduits is produced by intermittent jerks of the latter in the forward direction, followed by a slower return motion, the spiral-shaped cams 32 and 36 are mounted on the camshafts in the opposite sense, and the springs 34 and 38, which produce the jerks, are also arranged in opposite directions. In order to permit the necessary to-and-fro motion of the jacketed conduits, each of the inlet and outlet pipes has two balland-socket joints formed, for instance, of an upper part 2, an intermediate part 3, and a lower part 4.

The type of apparatus represented by Figs. 3 and 4 is also composed of two sections connected with each other in series. Each section is set in motion by a crank and a connecting-rod and is provided at the ends with telescopic or sliding joints. An intermittently-acting feeding device 41 supplies coal to a feed-pipe 42, communicating with the feed end of the upper conduit 43, which discharges the coal at the opposite end into a connecting pipe or canal 44, made of metal and lined with refractory material. From the lower end of the upright connecting-pipe 44 the coal enters the nearest end of the lower conduit 45, which discharges at the opposite end into a tower 46. The heatinggases enter the enlarged extremity 49 of the heating-jacket 50 of the lower section and travel through the same along helical deflecting-plates to the enlarged extremity 51, which communicates through an annular chamber 52 with an upright flue 53, formed on the canal 44 and leading to the enlarged inlet end 54 of the jacket 55. After having traveled through the latter on a continuous path determined by the deflecting-plates 77 the gas escapes through the enlarged outlet end 56 into an annular chamber 57, formed on the box 59 and communicating with the discharge-pipe 58. The box 59 communicates with the lower end of the feed-pipe 42 and receives any gases which may have been generated in the conduit 43 and which escape from the box 59 through a pipe 60. The conduit and jacket forming the upper section are supported by rollers 61, running on rails 62, supported by crossgirders 63. Reciprocating motion is imparted to the upper section in the known manner by a slotted crank 64 and a connecting-rod 65 and to the lower section by a slotted crank 66 and. connecting rod 67. 68 designates girders or frames which support the movable sectionsand to which are fixed the bearings of the rolleraxles. 69 designates girders which support the stationary feed-pipe 42, fuel-feeder 41, and box 59, and 70 designates girders supporting the stationary connecting-pipe or canal 44. The open ends of the movable sections are provided with telescopic or sliding joints. For instance, the inlet end. of the tube 43 has an annular boss 71, provided with a concentric groove or annular socket 72, into which fits a circular rib projecting from the face of the box 59. The open end of the tube 43 fits upon another circular rib placed concentrically within the rib mentioned above, so as to leave an annular groove between. A similar joint is formed at the outlet end of the tube 43, where 74 and 75 designate two concentric circular ribs projecting from the face of the canal 44 into the annular boss of the tube 43. Similar joints are formed at the ends of the jacket 43.

If the oscillating conduit is horizontal, means should be provided to insure that the material in the conduit will travel in the desired direction. For this purpose the interior of the conduit may be provided with one-sided teeth, such as the teeth 76, (shown in Fig. 1,) which are placed so as to point to ward the outlet end of the tube 5 and to thrust the material in that direction.

The temperature of the heat-interchanging fluid contained in the acket, usually hot gases, must of course be substantially different from the temperature of the material passin through the conduit.
